hive啟動metastore報錯：com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user ‘root’@‘node03’ to database ‘hive’

錯誤原因如下:

解決步驟:

• 首先進入msql命令列

  • msql -uroot -p*********

• 執行如下操作:

  ​ 注意這句要根據自己的資料庫名活用:grant all on 資料庫.* to ‘使用者名稱’@’%’ identified by ‘密碼’ with grant option;

  
  mysql> grant all privileges on *hive* to 'root'@'%' identified by '123456' with grant option;
  ERROR 1046 (3D000): No database selected
  mysql> grant all privileges on hive.* to 'root'@'%' identified by '123456' with grant option;
  ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
  mysql>
   
   set global validate_password_policy=LOW;
  Query OK, 0 rows affected (0.00 sec)
  
  mysql>  set global validate_password_length=6;
  Query OK, 0 rows affected (0.00 sec)
  
  mysql> grant all privileges on hive.* to 'root'@'%' identified by '123456' with grant option;
  Query OK, 0 rows affected, 1 warning (0.00 sec)
   
  
  
  mysql> flush privileges;
  Query OK, 0 rows affected (0.00 sec)
  
  mysql> exit
  

  • 然後重啟mysql

    sudo service mysqld restart
    

• 開啟metastore即可正常啟動了

bin/hive --service metastore &
